Brooke Gurland, MD, FACS
Clinical Professor, Surgery - General Surgery
BioPelvic floor and functional bowel disorders encompass a wide range of symptoms and conditions that affect people of all ages and genders. These include constipation, obstructed defecation, fecal incontinence, rectal prolapse, pelvic organ prolapse, irritable bowel disorders, and urinary and sexual dysfunction. While rarely life-threatening, these conditions profoundly affect quality of life, self-confidence, and daily function — and they deserve the same serious, compassionate attention as any other illness.
I am a colorectal surgeon and lifestyle medicine physician specializing in anorectal disorders and pelvic floor dysfunction. I serve as Research Director of the Stanford Pelvic Health Center, where I lead a multidisciplinary program that brings together colorectal surgery, urogynecology, urology, gastroenterology, and pelvic floor physical therapy to provide integrated, whole-person care.
My surgical training was at Cleveland Clinic, where I spent nearly a decade building and leading a multidisciplinary pelvic floor clinic and performing hundreds of combined procedures with colleagues in urology and urogynecology. I was among the early adopters of robotic surgical techniques for women with combined vaginal and rectal prolapse, and developed expertise in complex procedures including repair of intestinal and rectovaginal fistula. Earlier in my career, I established a Pelvic Floor Center at Maimonides Medical Center, where I received a Jahnigan Career Development Award studying multicompartment prolapse in elderly women. I joined Stanford's Department of Surgery, Division of Colorectal Surgery in 2017.
My research spans surgical outcomes, pelvic floor quality of life, and patient-centered technology. I am the principal investigator for the Stanford Pelvic Health Registry, a longitudinal database of over 475 patients with rectal prolapse followed since 2018. I was a 2020–2021 Stanford Biodesign Fellow, and my current work includes development and validation of disease-specific patient education tools. I believe that patients who understand their condition make better decisions — and recover better too.
I am also board-certified in lifestyle medicine. Prevention, diet, exercise, pelvic floor physical therapy, and behavior change are not secondary to surgery in my practice — they are the first line of care. Surgery, when it is needed, works best in patients whose lifestyle has been optimized. This philosophy guides how I counsel patients and how I train the next generation of surgeons and clinicians.
When I am not in the clinic or operating room, I can be found at the farmers market, fermenting something in my kitchen, practicing yoga, or spending time with my dog. -

Nicholas Haber
Assistant Professor of Education
Current Research and Scholarly InterestsI use AI models of of exploratory and social learning in order to better understand early human learning and development, and conversely, I use our understanding of early human learning to make robust AI models that learn in exploratory and social ways. Based on this, I develop AI-powered learning tools for children, geared in particular towards the education of those with developmental issues such as the Autism Spectrum Disorder and Attention Deficit Hyperactivity Disorder, in the mold of my work on the Autism Glass Project. My formal graduate training in pure mathematics involved extending partial differential equation theory in cases involving the propagation of waves through complex media such as the space around a black hole. Since then, I have transitioned to the use of machine learning in developing both learning tools for children with developmental disorders and AI and cognitive models of learning.

Stephen Haber
A.A. and Jeanne Welch Milligan Professor, Senior Fellow at the Hoover Institution and at the Stanford Institute for Economic Policy Research, Professor of History and, by courtesy, of Economics
BioStephen Haber is the A.A. and Jeanne Welch Milligan Professor in the School of Humanities and Sciences at Stanford University, the Peter and Helen Bing Senior Fellow at the Hoover Institution, and senior fellow at the Stanford Institute for Economic Policy Research. In addition, he is a professor of political science, professor of history, and professor of economics (by courtesy).
Haber has spent his career investigating why the world distribution of income so uneven. His papers have been published in economics, history, political science, and law journals.
He is the author of five books and the editor of six more. Haber’s most recent books include Fragile by Design with Charles Calomiris (Princeton University Press), which examines how governments and industry incumbents often craft banking regulatory policies in ways that stifle competition and increase systemic risk. The Battle Over Patents (Oxford University Press), a volume edited with Naomi Lamoreaux, documents the development of US-style patent systems and the political fights that have shaped them.
His latest project focuses on a long-standing puzzle in the social sciences: why are prosperous democracies not randomly distributed across the planet, but rather, are geographically clustered? Haber and his coauthors answer this question by using geospatial tools to simulate the ecological conditions that shaped pre-industrial food production and trade. They then employ machine learning methods to elucidate the relationship between ecological conditions and the levels of economic development that emerged across the globe over the past three centuries.
Haber holds a Ph.D. in history from UCLA and has been on the Stanford faculty since 1987.
From 1995 to 1998, he served as associate dean for the social sciences and director of Graduate Studies of Stanford’s School of Humanities and Sciences. He is among Stanford’s most distinguished teachers, having been awarded every teaching prize Stanford has to offer. -
Pardes Habib
Instructor, Neurosurgery
BioPardes Habib, MD/PhD, is an Instructor in the Department of Neurosurgery at Stanford University School of Medicine. His research focuses on how human neural stem cells (hNSCs) drive brain repair after chronic stroke. By integrating state-of-the-art imaging (MRI/PET) with spatially resolved multi omics, he maps structural and molecular remodeling after stroke and aims to identify diagnostic and prognostic biomarkers that drive the development and refinement of precision, cell-based therapies.
Dr. Habib completed dual doctorates in Neurology/Neuroscience (MD/PhD) and Biochemistry (PhD) at RWTH Aachen University in Germany, where he later earned a Habilitation (Venia Legendi) in Experimental Neurology—an academic qualification comparable to an associate professorship.
As head of Aachen’s Translational Stroke Research Group, he investigated neuroprotective and neuroinflammatory pathways and illuminated the roles of inflammasome activation and the unfolded protein response in acute ischemic stroke.
Since joining Dr. Gary Steinberg’s laboratory at Stanford in 2022, Dr. Habib has focused on decoding the molecular crosstalk among hNSCs, immune cells, and host neural circuits. His long-term goal is to transform these insights into targeted interventions that restore function and quality of life for patients living with the aftermath of stroke. -

BioI’m an applied economist with interests in employment, technology, competition, and economic policy in the aggregate economy and in particular markets.
I served as President of the American Economic Association for the year 2010. I presented the Ely Lecture to the Association in 2001 and served as Vice President in 2005. I’m a member of the National Academy of Sciences, Distinguished Fellow of the AEA, and fellow of the American Academy of Arts and Sciences, the Econometric Society, and the Society of Labor Economists.
Along with my Hoover Institution colleague Alvin Rabushka, I developed a framework for equitable and efficient consumption taxation. Our article in the Wall Street Journal in December 1981 was the starting point for an upsurge of interest in consumption taxation. Our book, The Flat Tax (free download from the Hoover Institution Press) spells out the proposal. We were recognized in Money magazine’s Hall of Fame for our contributions to financial innovation.
Marc Lieberman and I have a college textbook, Economics: Principles and Applications, now in its sixth edition.
I also served as director of the research program on economic fluctuations and growth of the National Bureau of Economic Research from 1977 through 2013. I continue to serve as chairman of the Bureau's Committee on Business Cycle Dating, which maintains the semiofficial chronology of the U.S. business cycle.
I have advised a number of government agencies on national economic policy, including the Justice Department, the Treasury Department, the Federal Reserve Board, and the Congressional Budget Office, where I serve on the Advisory Committee. I served on the National Presidential Advisory Committee on Productivity. I have testified on numerous occasions before congressional committees concerning national economic policy.
Before coming to Stanford’s Hoover Institution and the Department of Economics in 1978, I taught at the Massachusetts Institute of Technology and at the University of California, Berkeley. I was born in Palo Alto, attended school there and in Los Angeles, received my B.A. from the University of California, Berkeley, and my Ph.D. from the Massachusetts Institute of Technology.
In a 1976 paper, I introduced the distinction between fresh-water and salt-water economists. Bloggers using these terms are asked to contribute $1 to a fund that sends graduate students to MIT for one year and to the University of Minnesota for a second year.

Philip C. Hanawalt
Dr. Morris Herzstein Professor in Biology, Emeritus
Current Research and Scholarly InterestsMy current interest includes two principal areas:
1. The molecular basis for diseases in which the pathway of transcription-coupled DNA repair is defective, including Cockyne syndrome (CS) and UV-sensitive syndrome (UVSS). Patients are severely sensitive to sunlight but get no cancers. See Hanawalt & Spivak, 2008, for review.
2. Transcription arrest by guanine-rich DNA sequences and non-canonical secondary structures. Transcription collisions with replication forks. -

Frank Hanley
Lawrence Crowley, M.D., Endowed Professor of Child Health
Current Research and Scholarly InterestsHis research and clinical work focuses on the development of interventional techniques for fetal and neonatal treatment of congenital heart disease, pulmonary, vascular physiology, and the neurologic impact of open-heart surgery. He developed and pioneered the unifocalization procedure, in which a single procedure is used to repair a complex and life-threatening congenital heart defect rather than several staged open-heart surgeries as performed by other surgeons.

Maha Hanna
Clinical Assistant Professor, Pediatrics
Current Research and Scholarly InterestsA bad latch means maternal excruciating pain, ineffective milk transfer with subsequent weight loss, hypoglycemia, higher risk of hyperbilirubinemia and dehydration fever.All of the above led to early cessation of breastfeeding; 46% of mothers who initiate exclusive breastfeeding stop within the first 12 weeks because of difficult latch. I developed a latch tutorial focusing on step-by step-in striations for achieving an effective, non-painful latch.
